Multi-tenant commerce intelligence SaaS — sales, marketing, inventory, and profit for every shop in one source-aware workspace.

• Compares sales, profit, customers, and inventory across multiple shops — net sales, contribution margin, ad spend, MER, and product-level results in a single view.
• Integrates Shopify, Meta Ads, Google Ads, GA4, Amazon, GoKwik, and Dcluttr, keeping attributed advertising revenue cleanly separated from store sales.
• Surfaces stock risks, stale data, failed syncs, and reconciliation issues through a dedicated data-health layer, with owner, admin, analyst, and viewer roles per workspace.

Production-grade Shopify subscription management platform with Razorpay payment integration.

• Built a multi-section admin dashboard covering subscriptions, billing cycles, customers, orders, plans, issue tracking, webhook logs, analytics, and sync workflows — all in a single embedded Shopify app.
• Integrated Shopify OAuth, a storefront subscription widget, a customer portal for self-service management, and end-to-end Razorpay Checkout with webhook signature verification.
• Designed idempotent order creation logic ensuring Shopify fulfilment is triggered only after confirmed Razorpay payment events — preventing duplicate orders across retries and webhook replays.

Wi-Fi NeoPixel lighting system that turns any room into a synchronized, music-reactive light canvas.

• Near-zero latency path — native WASAPI loopback capture (no driver install), 60fps render loop, UDP pixel transport, and an adaptive look-ahead beat scheduler that lands light changes on the audible beat.
• ML DJ auto-mode detects BPM, genre, and energy live, switching between 25 built-in club effects on downbeats — chases, whips, phase waves, and strobe bursts run across the room strip-by-strip like a real fixture rig.
• Production-grade node firmware: clock-synced presentation with <2ms inter-node skew, streaming SHA-256 verified OTA updates, current limiting, watchdog, and a captive-portal setup wizard with Wi-Fi AP fallback.

Custom operations terminal and monitoring layer for automated crypto trading infrastructure, with a companion mobile app.

• Organised trading visibility around a live equity curve, open positions, per-strategy P&L, and market-regime signals — replacing raw terminal access with a structured, real-time interface.
• Built with a risk-first product philosophy: dry-run validation, daily loss limits, max-open-trade caps, ML confidence gating, and a circuit breaker enforced before any live strategy runs.
• Ships as a web dashboard and a Capacitor-packaged Android app with biometric unlock and push notifications, plus Telegram control for monitoring on the move.

3D printing product line with 247 published designs — cake toppers, celebration pieces, decorative prints, and custom orders.

• Published 247 original designs on Cults3D under the dknprints profile — including personalised cake toppers, anniversary pieces, birthday designs, keychains, and decorative wall art.
• Manages the full design-to-delivery pipeline: CAD modelling, STL export and repair, slicer optimisation, print production, quality review, and customer fulfilment.
• Accepts custom 3D printed product commissions, prototype support, and print-ready STL file preparation for clients with their own hardware.

Attendance analytics desktop application for small businesses running generic fingerprint attendance hardware.

• Ingests multi-format TXT logs from any fingerprint attendance device, automatically handling UTF-16/UTF-8/Latin-1 encoding variations, duplicate punch records, and incomplete day entries.
• Comprehensive analytics suite covering daily, weekly, and monthly attendance trends; per-employee hours worked; late arrival detection against configurable office hours; and an interactive calendar heat-map view.
• Ships as a single Windows .exe built with PyInstaller — no Python installation or runtime dependencies required, enabling immediate deployment to non-technical HR managers and office administrators.

Fully autonomous NSE options trading system with ML-based signal filtering and Telegram remote control.

• Five autonomous intraday strategies — OI Spike Scalp, Opening Range Breakout, VWAP Reversion, 0DTE Expiry plays, and Gap Fill — each with time-eligibility windows, duplicate position guards, and per-strategy risk limits enforced before any order is placed.
• XGBoost ML model trained on 86+ engineered features (volatility regime, VWAP distance, RSI, MACD, session phase, ATR, Bollinger Bands) dynamically adjusts lot sizing or blocks trades that fall below confidence thresholds.
• Complete Telegram control centre — live P&L snapshots, open position monitoring, circuit breaker status, risk dashboard, daily EOD reports, and live config updates via /set commands with no redeployment required.
